Specific embodiment
The direct plug element 1 of preferred the first embodiment by the present invention is retouched in detail referring to Fig. 1 and 2
State.
It can be seen from figure 1, the direct plug element 1 of the first embodiment includes direct contact 2, the direct contact
It is electrically connected on cable 7.Directly contact 2 is arranged in housing 3.Additionally, directly contact 2 symmetrically constitute with regard to plane E and
Including the first spring region 4 and second spring region 5.Directly the here of contact 2 has substantially U-shaped structure, wherein the first bullet
Spring region 4 is arranged in first support arm 21, and second spring region 5 is arranged in second support arm 22.
Additionally, two spring regions 4,5 have identical geometry, wherein the first spring region 4 includes spring arch 41
And second spring region 5 includes spring arch 51.It is provided with point type contact 40,50 in the flex point of spring arch 41,51 respectively.Institute
State point type contact here for example can be made up by means of punching course of the material of spring arch 41,51.
Such as from Fig. 1 can with it is further seen that, the first spring region 4 by the point type contact 40 on the first spring arch 41 with
Electric contact 60 is contacted.The open ground of electric contact 60 is arranged on printed circuit board 6, is carried out directly such that it is able to pass through point type contact 40
Contact.
Therefore the direct contact 2 of the first embodiment has two spring regions, so as to without any problems for directly slotting
Plug member 1 equips direct contact, because directly contact can reverse 180 °, and however can correctly assemble.Thus it is straight
It is favourable for the miniaturization that contact point connects particularly with direct connector.
Fig. 3 shows the direct plug element of second embodiment by the present invention, wherein identical or in function phase
With part with the identical reference in the first embodiment representing.
Housing, the direct plug element 1 of second embodiment is not shown for simplicity reasons in second embodiment
Including substantially U-shaped direct contact 2, the direct contact has the first spring region 4 and second spring region 5.First spring
Region 4 is provided with spring arch 41 with similar in the first embodiment.And second spring region 5 is then as the region being punched by straight
The material of the second support arm 22 of contact point is made.Here, such punching second spring region 5 so that the of the first spring region
The second elastic force F2 in one elastic force F1 and second spring region 5 points to identical direction（Referring to Fig. 3）.Here, direct the of contact
One support arm 21 is so constituted so that vicinity of the free end 21a of first support arm in second spring region 5.If existed now
The first spring region 4 deforms and thus first support arm 21 deforms during grafting, then the free end area of first support arm 21
Domain 21a just contacts with second spring region 5, and wherein free end 21a is bearing on second spring region 5.Thus so change
Straighten the general characteristic of contact point 2 so that contact elastic force is strengthened via free end 21 by second spring region 5.
In other side, this embodiment corresponds to embodiment above, such that it is able to reference to the explanation for being there given.
Show in Fig. 4 to Fig. 6 by the present invention the third embodiment direct plug element 1, wherein identical or
Person say function identical part with the identical reference in the first embodiment representing.For simplicity reasons,
Housing is equally saved in the direct plug element of three kinds of embodiments, so as to illustrate only the direct contact 2 of direct plug element.
As can be known from Fig. 5 and Fig. 6, direct contact 2 has substantially U-shaped structure again.
In particular such as figure 4, it is seen that directly contact 2 includes the first spring region 4 in first support arm 21, this
One spring region then has spring arch 41 and free end 21a.Free end 21a is inserted into all round closure of direct contact
In casing 23.Directly contact 2 is integrally formed and has in addition support region 24, and the support region can be clear such as from Fig. 6
It is used as the bearing-surface of first support arm 21 in the contact condition of direct contact as finding out to Chu.Thus prevent first
The overload of spring region 4 and the stress of the first spring region is reduced when there is peak excursion, so as to spring characteristic curve change
Obtain more constant（It is stable）.
In order to especially compensate to larger tolerance, the first spring region 4 is constituted in the following manner：In noncontact
In state（Figure 4 illustrates）, spacing A1 of spring arch 41 and second support arm 22 is at least the free end 21 of first support arm 21
It is double big with spacing A2 of second support arm 22（Referring also to the diagram of the spacing in Fig. 6）.The measure is outstanding during contact phase
Which obviate the plastic deformation of the first spring region 4, though so as in the connection of bearing-surface 24 repeatedly into and out
The damage of direct contact can also be avoided afterwards.In addition can ensure that by the measure, arrive in 0.3 in the first spring region 4
During typical spring travel in the range of 0.4mm, the elastic force F1 of 2N or bigger can be obtained.Here will be illustrated, in order to just
Direct contact 2 really is assembled, coding can be set in addition, such as vertically from casing 23 on the side of the first spring region 4
The region of upper protrusion.Thus the miniaturization of direct contact 2 can also be realized, without expecting loading error.
In fig. 5 and fig., show in phantom shape of the direct contact in the state of non-grafting.Then Fig. 5 shows
In a kind of state（21’）In first support arm 21, in a state first support arm 21 be just resisted against electric contact with offside
On, and then Fig. 6 shows the state in being pushed completely into（21’’）In first support arm 21, electricity is realized in a state
The directly contact of contact.
Additionally, directly the second spring region 5 of contact is arranged so as in second support arm 22 so that second spring region 5
Elastic force F2 be in reverse to the elastic force F1 of the first spring region.Additionally, the direct contact 2 of the third embodiment have two walls 25,
26, the two walls are spaced apart from each other in the following manner：First support arm 21 can enter into two walls 25,26 during directly contact
Between.The direct contact 2 of the third embodiment is preferably arranged the component being integrated.
In other side, the embodiment is corresponding to embodiment above, the reality being referred in terms of explanation before described
Apply example.
